I'm trying to do a post to a local url in my network using this
code, but I'm getting 401 error (HTTP/1.1 401 Unauthorized), what can I do? or search for? (the machine where I running this is out the domain)

    TMemoryStream *aStream = new TMemoryStream();
    TStringStream *StrStream = new TStringStream(NULL);

    TStringList *a = new TStringList();
    TIdURI *uri = new TIdURI("");
    TIdMultiPartFormDataStream *Params = new   TIdMultiPartFormDataStream();

    Params->AddFormField("tarjeta", codta);
    Params->AddFormField("tipo", tipo);
    Params->AddFormField("monto", monto);
    Params->AddFormField("cargo", cargo);
    Params->AddFormField("idcajero", idcajero);
    Params->AddFormField("cajero", cajero);

    IdHTTP1->Request->Clear();
    IdHTTP1->Request->BasicAuthentication = true;
    IdHTTP1->Request->Username = txtUser->Text;
    IdHTTP1->Request->Password = txtPwd->Text;

    IdHTTP1->Post(txtUrl->Text, Params, aStream);

    aStream->Seek(0, soFromBeginning);
    aStream->SaveToStream(StrStream);
    StrStream->Seek(0, soFromBeginning);

    ShowMessage(StrStream->DataString);

    delete a;
    delete aStream;
    delete Params;
    delete uri;
    delete StrStream;

The server requires authentication that you are not providing.  Make sure 
you have included the appropriate IdAuthentication...hpp header file into 
your code, such as IdAuthenticationDigest.hpp.

Thanks Remy for you help.

Well, first you need to find out which authentication(s) the server supports 
in the first place.  After the server's reply comes back, you can look in 
the Response->WWWAuthenticate property to see which authentication(s) the 
server asked for.

Hi Remy,

The server send this to me:

HTTP/1.1 401 Unauthorized
Content-Length: 1539
Content-Type: text/html
Server: Microsoft-IIS/6.0
WWW-Authenticate: Negotiate
WWW-Authenticate: NTLM
MicrosoftOfficeWebServer: 5.0_Pub
X-Powered-By: ASP.NET
Date: Sat, 26 Apr 2008 03:37:40 GMT
Connection: close

I see that is using NTML, but I don't know what is 
WWW-Authenticate: Negotiate


What can I do?

You did not say which version of Indy you are using.  Indy 9 does not 
support "Negotiate" at all, but it does support ""NTLM".  Indy 10 supports 
both.  Both Indy 9 and 10 have IdAuthenticationSSPI ("NTLM" in Indy 9, 
"Negotiate" and "NTLM" in Indy 10) and IdAuthenticationNTLM (just "NTLM" in 
both) units available.
